2 men saw a girl wearing a short skirt and sitting down 50 meters away with her legs wide open.
The 1st guy said, "Ahh, you can see she's wearing black panties."
The 2nd guy said, "No lah, I bet you she's not wearing any panties, and that black-black stuff is her bushy pubic hair!"
So the two guys started betting on who was right. To settle the bet, they asked a neutral 3rd guy to go nearer the girl to check it out.
So the 3rd guy went next to the girl, pretended to drop something on the floor, bet over to pick it up, and duly went back to the two guys to report his findings.
The two guys asked eagerly, "So who is correct? Who wins the bet?"
The 3rd guy replied, "Fuck lah. That's not black panties. That's not bushy pubic hair. That's a swarm of thousands of houseflies!"
